1 Claim.

The present invention relates to air registers and more particularly to pedally operated air registers or dampers.

The primary objects of the instant invention are to provide a device of the general character above indicated whereby the valve of a baseboard register or damper may be pedally rather than manually operated; to provide such a device whose pedal is disposed adjacent the lower portion of the register or damper; to provide such a device whose pedal is vertically movable; to provide such a device having a plurality of articulated links operable by the pedal for opening and closing the valve; and, to provide such a device which is simple in construction, is readily and conveniently actuated and which is reasonably economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawings, wherein Figure 1 is a fragmentary perspective View of the register or damper partly broken away to show its operating mechanism;

Figure 2 is a fragmentary front elevational view thereof; and

Figure 3 is a sectional view on line 33 of Figure 2.

Referring then to the drawings wherein like parts of the device shown are designatedby the same numerals in the several views, the pedally operable valve of the register or damper there shown and which is adapted for disposition adjacent an air vent, comprises a shell of sheet metal or the like generally designated I0, having an arcuate head II, the face of which shell is provided with a plurality of horizontally disposed louvers l2 for emitting air from the air vent, not shown.

The opposite ends of the shell 10 are each provided with a vertically disposed finishing member l3 of sheet metal or the like and medially of the shell is a vertically disposed member l4 separating the register or damper into two halves and hiding the articulated pedally operable articulated linkage.

Secured to the inner side of the member M as by spot welding is an angle sheet metal member [5 provided with a vertically disposed slot I6 and likewise secured to the inner side of the member I4, preferably in the same manner is an angle sheet metal bracket l1, all as best shown in Figures 1 and 3.

A link 3, pivotally connected at its upper end to the bracket 1'! is connected to a bell crank lever l9 medially thereof, the upper end of which bell crank lever is pivotally connected to a sheet metal bracket 20!] secured to the inner side of a swingable valve 2! and the lower end of which is pivotally connected to the upper end of alink 22 provided at its lower end with an angularly disposed pedal 23.

The link 22 at the inner end of its pedal 23 is provided with a transverse pin having an end thereof disposed within the vertical slot I6 whereby elevation of the pedal 23 from its position shown will swing the valve 2| from its closed position inwardly and thereby permit a flow of air from the vent through the louvers l2 and depressing of the pedal 23 to its position shown will effect a closure of the valve 2|, preventing a flow of air from the vent through the louvers, the housing 25 secured to the inner side of the shell ll] providing an air seal when the valve is closed.

It will thus be seen that the pedally operable register or damper is simple in construction, may be readily and conveniently actuated and is reasonably economical in manufacture, and while but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claim.

I claim:

A device of the class described comprising a shell adapted for disposition adjacent an air vent and provided with a plurality of louvers, said shell having a bracket secured thereto on its inner side and having a member secured on its inner side provided with a, vertically disposed slot, a valve member disposed rearwardly of said shell provided with a bracket, a bell crank lever pivotally connected to said second bracket, a link pivotally connected to the other end of said lever provided at its other end with a pedal disposed forwardly of said shell and having a pin disposed within said slot, and a link secured to said first bracket at one end thereof and to the bell crank lever at its other end whereby the valve may be opened or closed by the vertical movement of the pedal.
